Hey,

Was reading the TropicalFishHobbyist magazine on the AGA convention and Mr Amano.

In one of the setup which Mr Amano did, he uses a combination of MH, Compactfluroscent. Of which the MH comes on at different timings, increasing the light intensity.

From what i have read, linked to the AGA convention, it was done so to simulate the "high light" of the afternoon sun for the red plants.

My questions are,

1. does it help? does it speed up plant growth?

2. if so how would one fertilise such a tank ? ADA or generic brands ?
